We're dividing 637276 by 41 
The aim is to understand the frequency of 41 in 637276.

On to step 1:
41 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 41

On to step 2:
If we divide 63 by 41, we get 1 and a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 41 from 63 to get 22.
Include the next digit (7) from the dividend after 22, then repeat: 227 / 41

Advancing to step 3:
When dividing 227 by 41, we get 5 with a remainder of 22.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 205 from 227 leaves us with 22.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 41

Advancing to step 4:
41 can be fit into 222 5 times, resulting in a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 155.0
Subtract 205 from 222 to get 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 41

On to step 5:
The number 41 fits into 177 4 times, leaving a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 1554.0
Subtract 164 from 177 to get 13.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 41

Advancing to step 6:
41 goes into 136 3 times with a remainder of 13.
The next digit of our result is 3. 
Result so far: 15543.0
Deduct 123 from 136 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
When dividing 130 by 41, we get 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 15543.3
Subtracting 123 from 130 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
The number 41 fits into 70 1 times, leaving a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 15543.31
If we take 41 away from 70, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 9:
If we divide 290 by 41, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 15543.317
If we take 287 away from 290, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
30 divided by 41 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 15543.317
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
If we divide 300 by 41, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 15543.31707
If we subtract 287 from 300, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 12:
The number 41 fits into 130 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 15543.317073
Subtracting 123 from 130 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 13:
41 goes into 70 1 times with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 15543.3170731
The remainder is 29 after subtracting 41 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 14:
41 goes into 290 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 15543.31707317
The remainder is 3 after subtracting 287 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 15543.31707317, with a leftover of 3e-09.
